Hey! I don't know if someone got this issue or knows how to help:
I am doing a SQL query which is working fine:
// SELECT COUNT(DISTINCT "idVisit") FROM "test"
but when displaying an error appears
"Whoops! Expression failed with the message:
[math] > Unknown variable: country"
I don't know why this error appears (country is another variable in the dataset, but not one I'm interested in showing now) since this is not a variable I'm using in the SQL query.
Any help is appreciated!
